Optimised Display

[Astrikor]

Thanks dageci
You mean like this ?

import numpy as np
import os
 
def clearscr():
    os.system('cls' if os.name=='nt' else 'clear')
 
# in your code to clear the screen call this function
clearscr()
myarray = np.zeros([4,10])
print(myarray)
while True:
    for i in range(4):
        myarray[i,0] = 1 + myarray[i,0]
    print(myarray)
    clearscr()

Try it - it doesn't work!

Any other suggestions please?
